Specification of Letters Patent.

Patented June 1, 1915.

Application filed June 30, 1914. Serial No. 848,243.

To all whom it may concern:

Be it known that 1, JAMES C. Coss, acitizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vehicle Bow-Sockets, of

which the following is a specification.

My invention relates to improvements 1n vehicle bow sockets, and more particularly to improvements in tubular bow sockets for receiving and carrying the ends of the bows of tops, the present embodiment being particularly designed and adapted for use in connection with heavy vehicles, such as automobiles, or the like, where comparatively heavy tops are employed.

The primary object of the invention is to provide a generally.i'mprovedtubular bow tures particularly requiring tubular bow sockets of great strength and at the same timeof light weight so that the tops may be easily handled and at the same time thoroughly braced by the tubular bow sockets while in use. V j

The present improvements are particularly directed to strengthening and reinforcing the bow receiving ends of the tubular bow sockets so that these ends which are subjected to the greatest lateral stresses may be given the requisite strength and lightness and particularly may be prevented from breaking or splitting at the lateral seams or joints in the operation of driving the tapered ends of the wooden top bows into such receiving endsof the bow sockets, as now frequently occurs with the ordinary form of tubular bow socket.

WVith the above mentionedand' other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims. 1 i

Referring to the drawings, forming a part of this specification, Figure 1, is a side elevation of the bow receiving end of a tubular bow socket constructed in accordance with my invention. Fig. 2, an end view of the same. Fig. 3, a cross sectional View taken on line 3-3 of Fig. 1. Fig. 4:, a plan view of the blank for the particular form of reinforcing tie or bridge member employed at the bow receiving ends of the tubular bow sockets shown in the present embodiments of this invention. Fig. 5, a perspective view of the reinforcing or bridge members after being formed up and preparatory to being inserted over the jointed or seamed side of the tubular bow socket at the bow receiving end thereof preparatory to spot-welding or other suitable securing means. Fig. 6, a longitudinal sectional view of a slightly modified form of tubular bow socket in which the inner tube does not eX- tend entirely to the end of the bow receiving end of the socket. Fig. 7, a view illustrating the manner of spot-welding the reinforcing or bridgemember at the bow receiving end of the socket in connection with the electrodesof the welding apparatus.

Similar numerals of reference designate like partsthroughout all the figures of the drawings.

The improved tubular bow socket may be of the usual construction comprising an outer tubular member 1, suitably formed and preferably tapered from top to bottom and an inner or reinforcing longitudinally split tubular member 2, said outer tubular member being provided along one side with a double seam or joint l commonly known as a stove pipe lock with the projecting seam or portion rolled to the inside as shown most clearly in Figs. 2, 3, and'6 of the drawings.

The inner or reinforcing tubular member 2, is of such form and dimensions that when inserted and driven into the outer tube 1,

the side or longitudinally extending edges 2 will be spaced apart forming an intervening space or recess 2", to receive and contain the inwardly projecting portion of the double seam or joint 1*, said edges 2", being adapted to impinge on each side upon the projecting joint 1*, when the tube 2, is driven home thereby gripping the seam or joint 1*, and preventing any relative movement or displacement of the outer and inner tubes 1 and 2, respectively.

In. the construction of large heavy tops, such for exapmle,the one-man-top hereinbefore referred to, it is particularly important that the tapered ends of the wooden top'bows be driven or forced into" the bow receiving ends of the tubular bow sockets with great force in order that a perfectly rigid joint or connection may here occur, and in order to prevent the splitting of the tubular socket at the seam or joint l y as now sometimes occurs, and also to avoid unnecessarily adding tothe weight of this portion of the bow socket, I provide an improved reinforcing element or bridge member at this portion of the tubular bow socket shown in some of its embodiments in the drawings and hereinafter described.

The improved reinforcement or bridge member3, is adapted to be mounted transverselyralong one side and at the bowreceiving end of the tubular bow socket and to extend across the seam or joint I and may be welded, or otherwise suitably secured,,to

the walls of the tubular bow socket, prefer- V ably by spot-welding? as indicated at 3.

As a convenient form for carrying out this weldingprocess said reinforcement or bridge member 3,.is preferably cut from a blank as indicated in Fig. 4 of the drawings, so that when formed up as indicated in Fig. 5, inner and'o'uter reinforcing or bridge members 3, are provided, and as a means of holding said inner and outer'members in proper relative position for attachment, and more particularly as a means for holding said inner and I outer members 3, in proper alinement or registry with each other during the spot-welding operation as illustrated in Fig. 7 of the drawings, the sides of said inner and outer members 3,'are connected by means ofa con;

necting web portion 3, so that the spotwelding operation may be quickly and prop erlycarried out.

In practice, it has been found that when the bow receiving ends of the tubular bow sockets are vprovided Vwith these reinforcements applied and spot-welded as shown and described that such bow receiving ends 'of the tubular bow" sockets are given a surprising degree ofstrength so that it is practically impossible to split them in driving in the wooden bows, and it will be seen :that 'an exceedingly strong light weight tubular bow.

socket is provided, this 'great strength being particularly manifest where the inner split member extends-to the top of the bow receiving end of the socket and is connectedas shown in Figs. 1 and 3"of the drawings.

It will be observed also that the bow receiving end of the bow socket is greatly strengthened' and that the longitudinally extending seam is prevented from splitting or spreading apart,'aslikewise the edges'Q, of the inner split tubular member 2, by reason of the fact that the middle or intermediate spot Copies oi! this patent may De-obtained for weld extends through the double seam or joint 1 and that the outer spot welds on.
